ABSTRACT
The microscopic polyangiitis is a systemic necrotizing vasculitis that affects arterioles, capillaries and venules, but can also reach small and medium-sized arteries. It is considered a rare disease, idiopathic in nature but clearly autoimmune. Several ocular and systemic abnormalities are associated with retinal arterial occlusions. Among the collagen vascular diseases, the literature cited as possible causes of retinal artery obstruction lupus erythematosus, polyarteritis nodosa, giant cell arteritis, Wegener’s granulomatosis and lymphoid Liebow. Until now, there were no reports in the literature of the association of cases of arterial occlusion retinana associated with PAM. The authors report a case of a 53 years old patient diagnosed with microscopic polyangiitis who presented with important renal artery occlusion and associated unilateral central retinal artery occlusion. An extended systemic evaluation of patients presenting with central retinal artery occlusion should include research of PAM through analysis op p-ANCA.
